SPECIFICATION forming part of Letters Patent N o. 776,980, dated December 6, 1904. Application filed January l5, 1904, Serial No. 189,126. (No model.)

To (all Uf/"mm, it ntf/,y concer/t:

Be it known that l, EMIL AL'rMANN. a citizen et' the United States, and a resident ot Helena, in the county ot' Lewis and Clarke and State of Montana, have invented a new and Improved Elevator, of which the following is a i'ull, clear, and exact description.

The object oit' the invention is to provide a new and improved elevator' more especially designed for elevating grain and the like and which is simple and durable in construction, very eii'ective in operation, and arranged to take up comparatively little room, to allow oi' conveying a large amount ot material without requiring the running ot' the elevator at a high rate ot' speed, thus insuring long life to the elevator.

The invention consists of novel Features and parts and combinations of the same, as will be more fully described hereinafter, and then pointed out in the claims.

A practical embodiment of the .invention is represented in the accompanying drawing's, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a sectional side elevation of the improvement, parts being broken out. Fig. 2 is a transverse section of the same, and Fig. 3 is a perspective view oi' one ot' the buckets.

On a suitably-constructed framework A is journaled a shaft B, connected with other machinery for imparting a rotary motion to the said sha'tt B,and on the latter' are secured spaced sprocket-wheels (l, between which extends a chute l), having' its mouth 11)/ in close proximity to the inner open ends of elevator-buckets E, passing around the sprocket-wheels, so as to discharge their load into the mouth D/ of the chute l), connected at its lower end with a conveyor F otl any approved construction for carrying the material to the side et' the elevator.

Each of the buckets E has a tl-shaped bottom E and sides E2, the top edges ot' which are tlf-shaped for receiving the betteln ot' the next adjacent bucket to allow of nesting the buckets while on the up or down ru n, as plainly illustrated in Fig. l. The sides E2 oi each bucket are provided near the inner ends with top and bottom eyes E:z and E",ol which the bottorn eyes E4 ol a bucket lit against the eyes E;s of an adjacent bucket.v and the registering eyes E3 and Ei ol adjacent buckets are connected with each other by a pivot El. extending transversely and projecting beyond the eyes E3 to engage the sprockets on the sprocket-wheels C for the latter tp move the buckets around the sprocket-wheels and to cause the buckets to assume such angular position relative to the mouth D as to discharge'their loads as the buckets pass into an uppermost position. (See Fig. 1.)

By constructing the buckets in the manner described and connecting the same by the pivots E it is evident that an endless bucketchain is provided in which thebuekets nest in both the up and down runs, butin reversed position, on the down run, as will be readily understood by reference to Fig. l.

Vhen the elevator is in operation, the material is contained in the buckets on the up run by having' the buckets formed with V- shaped bottoms E', and when such a loaded bucket reaches the sprocket wheels C then the two pivots Ei on each bucket, by engaging corresponding sprockets on the wheels C, cause the corresponding bucket to assume gradually such position that one arm ot' the tl-shaped bucket extends horizontally while the other extends vertically, and when this position is reached the bucket is with its inner end opposite the mouth D ot' the chute .1), so that the material in the bucket can begin to discharge into the mouth D'. As the bucket advances the inclination ot' the bottom increases, so that all the material readily discharges into the mouth D. which extends somewhat beyond the center line o'lI the sprocketwheels C to receive all the material that is in the buckets.

From the foregoing it will be seen that but a few parts constitute the endless bucketehain, as the buckets themselves with the pivots form the connecting' members of the chain, and hence the bucket-chain is not liable to easily get out of order.

ln order to strengthen each bucket, suitable cross-bars E may be employed for connecting the sides E2 with each other near the top thereof, as plainly indicated in Figs. 1 and 3. By having the buckets open both at the inner and outer sides it is evident that the buckets can be readily charged at the outer sides while on the up run, and the inner open sides allow convenient discharge of the material into the mouth D of the chute D, as above explained. As the buckets are nested one in the other, it is evident that a large quantity or' g'rain or other material can be carried by the elevator without running the elevator at a high rate of speed, hence insuring long life to the elevator.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. An elevator having' buckets with V- shaped bottoms, and sides, the top edg'es of the sides of each bucket being' also V-shaped to tit the bottom of the bucket next above it, the inner side of each V-shaped bucket having near its inner end eyes above and below its side edges, the upper eyes of each bucket registering' with the lower eyes of the bucket next above it, transversely-extending pivots connecting the registering eyes of adjacent buckets with each other to form the buckets into a chain, said pivots projecting beyond the sides of the buckets, the relative position of said upper and lower pivot-points being such as to hold the buckets normally in a horizontal position, spaced sprocket-wheels engaging the projecting' ends of the pivots for carrying' the bucket-chain around and for causing the buckets to assume a discharge position, and a receiving-chute having its mouth extending between the wheels and into which chute said buckets discharge.,

Q. An elevator having a bucket chain formed oi' buckets with V-shaped bottoms and sides, the top edges of the sides of each bucket being also V- shaped to receive the bottom of the bucket neXt above it, said buckets being' nested together and held in horizontal position and pivots connecting said buckets together.

3. An elevator-bucket having a bottom V- shaped in cross section, sides V- shaped at their lower edges to conform to the bottom, and having V-shaped recesses in their Lipper edges to render the upper edges of the sides parallel with the lower edges thereof, crossbars at the upper sides oi' the bucket to brace the saine, and pivots for connecting a series of buckets together to form a bucket-chain.

4. An elevator-bucket having a bottom V- shaped in cross section, sides V-shaped at their lower edges to conform to the bottom, and having' V-shaped recesses in their upper edges to render the Lipper edges of the sides parallel with the lower edges thereof, opposing top and bottom eyes near the inner ends ot the bucket, and transverse pivots carried by said eyes and projecting' beyond the sides of the bucket.

In testimony whereof I have signed my name to this speciication in the presence of two subscribing' witnesses.
